SPECIFICATEON forming part of Letters Patent No. 307,474f, datedNovember e, 1884. Application filed March 22, 1884. (No modeli) To allwhom, it may concern:

Be it known that we, MELvrN D. Lnrrnnn and SrLAs V. BARLow, citizens ofthe United States, residing at Delavan, in the county of Valworth andState of Visconsin, have invented a new and useful Neck-Yoke, of whichthe following is a specification, reference being had to theaccompanying drawings.

Our invention relates to neck-yokes, theobto provide a device of .thischaracter which shall be self-adjusting to any desired length.

A further object of the invention is to equalize the pressure or suddenjar caused by any unevenness of the road by allowing the yoke to give tosaid motion, thus preventing any strain to the horses.

A further object of the invention is to provide a device of thischaracter which shall be simple in its construction, and durable, andthoroughly effective and certain in its operaion.

With these ends in view the invention consists in the combination oi atube or pipe of suitable dimensions with tubular extensions adapted toslide therein, and carrying rackbars to engage with a pinion looselymounted upon a shaft vof said pipe.

The invention further consists in the improved construction andcombinations of parts hereinafter fully described, and pointed out inthe claims.

In the drawings, Figure l is a perspective view of a neck-yokeconstructed in accordance with our invention, showing the tubularextensions laterally adjusted. Fig. 2 is a front view of the same,partly in section; and Fig. 3 is a perspective view of the tubularextensions and pinion detached. Fig. et is a cross section through thering. v

In the accompanying drawings, in which like letters refer tocorresponding parts in the several figures, A represents a neck yoke,which is constructed as follows:

B represents apipe or tube, the diameter of which is slightly enlargedat about its center. Vithin this pipe or tube are located slidingtubular extensions C, the ends of which are adapted to extend throughthe openings in the ends of the tube B. Upon the upper side of one ofthese tubular extensions C is suitably secured a rack-bar, D, while theother tubular extension is provided with va similar rack-bar securedupon itslower side. rIhe tubular extension which is provided with therack-bar upon its under side is provided with a longi tudinal slot orrecess upon its upper side, wh ile the extension carrying the rack-barupon its upper side is provided with a similar slot upon its lower side,in order that the rackbars, when the tubular extensions are closed, willrest within said slots, respectively, and thus occupy but aminimumlamount of room.

E represents a bolt passing through the enlarged portion of the tube B,and having sei cured upon one of its ends the pole-ring F. Upon thisbolt Eis loosely mounted a pinionwheel, G, which is held in positionagainst lateral movement on said bolt by means of washers, which arepreferably convex on their outer faces, thus conforming to the shape ofthe tube B. The ends of the tubular extensions C are closed by means ofa plug, which is secured therein by means of a bolt passing throughopenings in the said tubular extensions. The end of this bolt H is bentto form a loop, which carries the hame-ring l.

It will be seen from the above description that by the use of ourimproved neck-yoke, when the tongue or pole is moved laterally by reasonof the wheels striking a rut or obstruction in the road, the tubularextensions will automatically give to said motion and draw apart theextensions, thus relieving the horses from such strain. The extensionswill then resume their normal position.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-

l. A neck-yoke consisting of a tube or pipe, in combination withextensions adapted to slide therein, said extensions each carrying arack-bar adapted to mesh with a pinion mounted on a transverse bolt,washers mounted on said bolt and adapted to bear against the sides ofthe rack-bars, and a pole-ring secured to4 one or" the ends ot' saidbolt, substantially as set forth.

2. In a neck-yoke, the combination, with a suitably-constructed tube 0rpipe, of tubular IOO extensions carrying rack-bars, and provided 1ntestimony that Weolaim the foregoing as 1o with slots for the receptionof the `ends of the our own We have hereto afxed/ our signatures saine,a pinion-Wheel loosely mounted upon a in presence of two Witnesses.

shaft to gear with said rack-bars, Washers ins f l terposed between thesides of the pipe and the SB ,said pinion, and plugs mounted in the endsof f the extensions7 and a bolt passing through Witnesses:

said plugs and carrying the llame-rings, sub- A. H. KENDRIOK,

stantially as set forth. Y C; H. SHULZ.
